15 using it.

Anotherobject .is to so construct a device of this character that theparts may be readily separated for repairing or furnishing a `new bladewhen suchbecomes necessary.

In carrying out these objects, the invention is susceptible of a widerangeof modification without departing from the spirit or sacrificingany of the advantages of' the claimed invention; there 'being shown inthe drawings for illustrative purposes a preerred and practical form, inwhich:

Figure 1 representsA a perspective view of a portion oi acounter showingthis improved cutter in operative position; 3D

ber of the cutter, with the blade shown in ydotted line; l

Fig. 3 is a similar ber of the cutter; v y y Fig. l is ay transversesection taken on the line 4-l of Fig. 1 ,"and Y Fig. 5 is a similar viewtalien on the line V 5f-5 of' Fig. 1. `4 y In the embodiment illustratedthe cutter e@ 1() constituting this invention is shown lmounted on oneendof a table or count-er l which has a pin or rod 2 extendin g upwardlytherefrom preferably near the corner to rcceive and rotatably support aball 3 of twine et such as is ordinarily used in stores for tying uppackages.

The cutter 10 is composed of two members 11 and 15 slidably andseparably connected and between which is designed to be mounted E? thecutting blade 20. This blade 2O as shown view oi the other memis in theform of a safety razor bladehaving cutting edges along both top andbottem so as to be reversable when desired and pped with apertures 21 toreceive out struck tongues-12for1ned on the body of the member 11andwhich face in opposite directions as shown clearly in Fig. 2. so thatwhen the blade iszmounted thereon it will be heir. against slidingmovement. p. y

The member 11 is designed-to` be attached Vto the counter orothersupport by means of screws 22 passed through apertures 18 in thebody of the member 11.` lnturned flanges 14 are formed along the sideedges of the memberll which is preferably struclziout of sheet metal andthese flanges form guides to slidably receive the member 15. Alongitudinally extending slet-like opening 23 is formed on one edge ofthe member 11 and has a mouth 2li opening through said edge and forms inconnection with a similar opening 26 in the member 15 provided with amouth 27 a chamberto receive the cord A1 to be severed.

The plate or member 11 is made wider at l its front end than at the rearoi the opening 23 and the outlet or mouth 2e of said opening 1s locatedat the junction of the wider v i portion of this plate with the narrowportion Fig. 2 is a detail perspective otono mem-pk of the plate asisshown clcarlyin Figs. 1 and 2. Y

Member 15 is struck out oi: a sheet of metal with the body portionthereof outwardly bulged for the greater portion .of its length as shownat 16, saidbulged portion gradually merging at its inner end into thebody of the plate. This bulge-d -portion operates to space the membersapart'during their slidin@` engagement3 the edges of said plate 15 beingadapted to extend under and be guided by the inturned flanges 14 of themember 11. The wider portion'ot the plate 15 is designed to slide in theflanged edge 2510i the wider portion of the plate 11.

The upper edge of the wider portion `of late 15 is also'rprovided withan open` slot 26 provided with `a mouth 27 which'registers when theplates are in extreme retracted position, with the slot 23 of plate 11asis-shown. clearly in Fig. 1. This slot 26 as above de- (ffl scribedhas a mouth 27 at its inner end which registers with month 24 of plate11 and is designed to receive the cord to be cut by the blade 20 whichis clamped between the members 11 and 15 with its cutting edge pro-Yplate to slide freely without contacting or bindinef against said screwheads.

PTJ h l b In the use of this cutter the parts being assembled as shownin 1 and a ball of cord placed on the pin 2 with the free end 4lofsaidcore loose it will be understood that this cord end may be used to passaround bundle and tied; then bv simply inserting the portion beyond thetied bundle in the opening `in the upper edges of the plates enteredthroiigli the registering mouths 24 and 27 the cord may be moveddownwardly against Vthe sharp edge of the cutting blade 20 and quicklysevered.

Then it is' desired to reverse the cutting edge of blade 2O all that isnecessary is to drawoutwardthe plate or member 15, discngage the Abladefrom the tongues 12, reverse it and again reengage it and then replacethe vmember 15 which kwill clampingly hold said blade in operativeposition again ready for use.

f rlhe extreme simplicity of this deviceand the fact that old safetyrazor blades may be used to form the severing element2() renders theupkeep of the device practically nil. Moreover with the blade housedbetween the two members 1l and 15a-ind having the cutting edgethereofextended upwardly from the lower walls of the registeringopenings said bladeis protected against being injured itself and alsoagainst Contact with persons using it.

lVitliont further description it `isvtliought that the vfeatures andadvantages of the' invention will berreadily apparent to those skilledinthe art,r and it will, of course,rbeV

understood that changes in the form, proportion and minor details ofconstructionv may be resorted to, without departing from the spirit ofthe inventionr or its scopeas claimed.

I claim:

LA cord cutter comprising Ia. pair of clamping plates arranged onev onthe other in sliding relationand having means tojhold Qthein againstseparation, said plates each having aiecess opening through one sideedge and extending longitudinally of the plate, said recesses beingadapted to register Qwhenthe plates are brought to -a predeterminedposition,l a cutting blade clamped between said plates with its cuttingedge extending iiito said recesses, one of said plates having a transvezsely arran ged tubular ineinber to forni a hand grip.

2. A cord cutter comprising a pair of clamping plates adapted. to bearranged one on the other and to slide longitudinally in relation toeach other, one of said plates have ing inturned flanges along its sideedges to -forin guiding means for the other, both of said plates havingone end ina-de wider than theother and said wide ends provided near oneedge with longitudinally extending open slots, the openings in saidslots being arranged at thel junction of the wide portions withthenarrower portions of the plates, and a blade to be clamped between saidplates with oneeege projecting into said slots.

3. A cord cutter comprising a pair of clamping plates adapted to bearranged one ontheother and to slide longitudinally in relation to eachother, one of said plates having inturned flanges along its side edgesto forni vguiding means `for the other, both of said plates having oneend made .wider than the otherand the said wide ends provided near theirupper edges with longitudinally extending open slots', `the openings insaid slots being arranged at the-junction of the wide portions with thenarrower portions of the plates, said open slots being adapted toregisterwhen the plates are in operative position, a blade to be clampedbetween said plates with one cutting edge projecting into said slotsnandmeans forsecuring. one of said plates toa support.

ll. A cord cutter comprising a pair of clamping plates adapted to bearranged one von the other and to slide .longitudinally in relationtoeach other, one of said plates having intnrned flanges to forni guidingmeans for the other, both of said plates having one end made wider thanthe other and said wide ends provided near their upper edges .with

.longitudinally extending slots open at one end, the openings in saidslots being arranged at the junction of .the wide portions .with thenarrower portions of the plates, said open slots beingadapted toregister when the plates are in operative position and to form a bladeseat, means for seciiringone of said plates to a support, and anoutwardly bulged poi'- tion inr onel plateto adapt it to move freelyover the securing ymeans of the other plate without contactingthem.
